Soldier and reproductive proportions of Reticulitermes flavipes (Kollar) were determined in sampling baits from 89 colonies and 5 logs. Soldiers averaged 2% of the colony and neotenics, when present accounted for up to 1.28%. The sex-ratio of R. flavipes neotenics was ca. 2 females for every male. Soldier proportions were always high in the vicinity of the neotenics.
